Strap for Classic Date Lady 28.5 Stainless Steel / Silver

The lug width is precisely 14mm, measured directly between the two pin-holes of the case. This measurement is standard for this reference and requires straps manufactured to strict tolerances between 13.8mm and 14.2mm, ensuring secure attachment without excessive play or friction.

For a 28.5mm case, vegetable-tanned calf leather is the optimal choice: it is sufficiently flexible, develops natural patina over time, and maintains balanced visual proportions. Genuine alligator remains excellent for formal occasions. FKM rubber is the most versatile solution for daily wear.

Position a ruler horizontally between the two pins that attach the strap to the case, excluding the case entirely. The distance must correspond to 14mm. Perform the measurement on both sides (although they should be identical) and ensure the ruler is perfectly perpendicular to the pins.

Yes, provided they are manufactured with a 14mm lug width. Generic straps may feature different tolerances or slightly larger measurements (14.2-14.5mm), causing loosening or installation difficulty. Milano Straps' artisanal straps are custom-made with manufacturing tolerances of ±0.3mm.

A vegetable-tanned calf leather strap, worn daily on an Oris Classic 28.5mm, maintains structural integrity for 18-24 months. Longevity depends on frequency of wear, climatic conditions (humidity accelerates degradation), and maintenance (monthly cleaning with damp cloth, annual treatment with natural conditioner). Alligator leather offers greater durability, up to 36 months.
